REMovABI-.E cAs-K-covna Application ledl. June 13,

To allwrom t may concern;

Be. itknown that I, JOHN L. KoLBE, a citizen of the-United Statesof America-7 residing at Crookston, in the county-of Polk andt Stateof Minnesota, have invented new and useful Improvements in Removable Cask,- Covers, of" which the 'following `is aspeciiication.

The objectofthe invention is toy provide a cask cover which is adapted to be removed and replaced withouty the use of auxiliary fastening means or of devices serving to mutilate or involving permanent engagement with the cask walls, and adapted when removed to leave the walls of the cask unobstructed, and at the same time to provide a device of this character wherein substantial engagement with the cask is secured when the parts are properly positioned, so as to prevent accidental and surreptitious removal or displacement thereof.

Further objects and advantages will appear .in the course of the following description of a preferred embodiment of the invention, it being understood that changes in form, proportions and details may be resorted to within the scope of the claim without departing from the principles involved.

In the drawings:

Figure 1 is a plan view of a cask cover embodying the invention, applied in the operative position to a cask.

Fig. 2 is a sectional view of the same on the plane indicated by the line 2-2 of Fig. 3 is a. sectional view at right angles to the plane of F ig. 2 as indicated by the line 3*?) of Fig, 1.

Fig. -t is a plan view of the cover as seen when collapsed or with its parts disposed for removal from the cask.

Essentially the improved Cask top or cover consists of the corresponding segmental members 10 and 11 each of which is of such dimensions as to represent somewhat less than one-half of the area of the top of the casing 12 which said cover is designed to fit. the facing straight edges of said members being provided with guide grooves 13 for the reception of the side edges' of sliding elements 14 adapted in the positioning of the cover to be moved from an intermediate position indicated in Fig. 4 to terminal positions indicated in Fig. 1, and a key element 15 adapted to be fitted into the space between the facing edges of said seg- Speci'cation of Letters Patent.

mental; members and in the inner extremities of said. sliding elements after the latter hm'ebeenmoved to their terminal or normal positions, tolock the latter in said positions and thus prevent the collapsing and removal of the cover.

In theconstruction illustrated the segmental members preferably consist of T-frames having the longitudinal spaced bars 16 and transverse bars. 17 supporting a filler 18 whichis disposed between the planes of said frames as indicated more clearly in Figs. 2 and 3. The peripheral edges of the fillers are chamfered as shown at 19 for engagement with the chime of the cask. rlhe grooves 13 at the inner straight edges of the segmental members are formed by the spaces between the inner edges of the longitudinal bars 16, and the bottoms or inner walls of these grooves are preferably inclined from their centers toward their extremities to form outwardly convergent guides 20. The sliding' elements 14 are similarly tapered toward their outer ends so as to these convergent walls of the guide grooves and act as wedges in forcing the segmental members of the cover to their proper positions in peripheral engagement with the chimes of the casing. The outer edges of the elements 11 are chamfered as at 2l to correspond with the peripheral edges of the segmental members.

VThe key member consists of elongated blocks 22 and 23 of which the former is located when in operative position in the plane of the longitudinal bars 16 of the segmental members indicated in Fig. 3 while the member 23 is located in the plane of the sliding elements 14 so as to lock the latter against inward displacement as shown in Fig. 2. The key member is held in place by means of a turn button 24 pivotally mounted as at 25 and adapted for terminal engagement with keepers 26 secured respectively to the upper surfaces of the bars 16 of the segmental members.

As a further means of preventing accidental displacement of the parts of the cover and to guard against surreptitious removal of the same a sealing wire 27 may be eX- tended through registering openings 28 and 29 formed in the longitudinal members 16 and the element 22 of the key member and having a seal 30.

' Obviously the removal of the cover may be accomplished by disengaging the turn Patented Nov..30, 1920..

Claimed A caslr cover embodying companion segmental members each of less than one-half the area of the top of the Cask to be closed,

and embodying T-t'rarnes consisting of longitudinal spaced bars, transverse bars connecting with the longitudinal space bars at the center of the latter and supporting iillers disposed between the planes of said frames and having their peripheral edges cham- JIered for engagement With'the chime of the cask and being formed with grooves adjacent the longitudinal bars, the bottom or inner Walls of the grooves being inclined from their centers toward their extremities to `form outwardly convergent guides, tapering sliding elements bearing toward their outer end to bear on the converging walls of the guide grooves and chamfered on'their outer edgesto correspond' with the peripheral edges of the fillers, a kev member consisting of elongatedblocks of whichv one when located in operative position is disposed in the plane of the longitudinal bars and the other located in the planeet the slidingelements to lock the latter in their outermost position, and a turn button and retaining means therefor by which the said key member is held in operative position.

ln testimony whereof I affix my signature.
